带圆弧矩形编程怎么编的

Python 使用 Pygame 库

```python

import pymunk

import pymunk.pygame_util

import pygame

初始化 Pygame 窗口

screen = pygame.display.set_mode((600, 600))

clock = pygame.time.Clock()

创建空间并设置重力

space = pymunk.Space()

space.gravity = (0, -900)

设置长方形的四个圆弧半径

radius = 20

创建四角圆弧的形状

verts = [(-100 + radius, -radius), (-radius, -radius), (-radius, radius), (radius, radius)]

shape = pymunk.Poly.create_from_points(verts)

shape.friction = 0.5

space.add(shape)

while True:

for event in pygame.event.get():

if event.type == pygame.QUIT:

pygame.quit()

return

screen.fill((255, 255, 255))

space.debug_draw(screen)

pygame.display.flip()

clock.tick(60)

```

C++ 使用 MFC

```cpp

CDC *pDC = new CClientDC(this);

CBrush brushGreen(RGB(0, 255, 0));

CBrush* pOldBrush = pDC->SelectObject(&brushGreen);

CPen penBlack;

penBlack.CreatePen(PS_SOLID, 3, RGB(255, 0, 0));

CPen* pOldPen = pDC->SelectObject(&penBlack);

CRect rect;

GetClientRect(rect);

rect.DeflateRect(60, 60);

pDC->RoundRect(rect, CPoint(20, 20));

pDC->SelectObject(pOldBrush);

pDC->SelectObject(pOldPen);

brushGreen.DeleteObject();

penBlack.DeleteObject();

```

JavaScript 使用 HTML5 Canvas
